Researchers give 2D electronics a performance boost

Two dimensional (2D) semiconductors have a unique property that allows their thickness to be reduced to one or few atoms—and this property could potentially minimize the short channel effects that remain an issue in advanced ...

Porous crystals bind fluorine-containing greenhouse gases

Emissions of greenhouse gases contribute significantly to global warming. Not only carbon dioxide (CO2) but also fluorine-containing gases—including so-called per- or polyfluorinated hydrocarbons, or PFCs—have a significant ...

Organic TFTs exhibiting band-like transport

Organic thin-film transistors (OTFTs) are the basic building blocks for flexible and stretchable electronics. As organic semiconductor films usually contain significant structural and energetic disorder, charge carriers hop ...

Cooking up a conductive alternative to copper with aluminum

In the world of electricity, copper is king—for now. That could change with new research from Pacific Northwest National Laboratory (PNNL) that is serving up a recipe to increase the conductivity of aluminum, making it ...

Making dark semiconductors shine

Whether or not a solid can emit light, for instance as a light-emitting diode (LED), depends on the energy levels of the electrons in its crystalline lattice. An international team of researchers led by University of Oldenburg ...

Sharp X-ray images despite imperfect lenses

X-rays make it possible to explore inside human bodies or peer inside objects. The technology used to illuminate the detail in microscopically small structures is the same as that used in familiar situations—such as medical ...

Tunable quantum traps for excitons

Researchers at ETH Zurich have succeeded for the first time in trapping excitons—quasiparticles consisting of negatively charged electrons and positively charged holes—in a semiconductor material using controllable electric ...
